The Big Bang Theory is one of the most informative and hilarious TV series America has ever produced. At first, for me, it was quite difficult to understand; I have never been a fan of physics and math, but I decided to continue watching it and I still didn’t regret it.

The Big Bang Theory tells the story of four friends. Leonard Hofstadter (Johnny Galecki) and Sheldon Cooper (Jim Parsons) are both brilliant physicists working at Cal Tech in Pasadena, California. They are colleagues, best friends and roommates. Sheldon has non-conventional ways and always tests his roommate and friends and colleagues, mechanical engineer Howard Wolowitz (Simon Helberg) and astrophysicist Rajesh Koothrappali (Kunal Nayyar) .

Their daily routine is working on their individual work projects, playing video games, watching science fiction movies or reading comic books. No women or social activities. All this changes though when Penny (Kaley Cuoco), a pretty woman and an aspiring actress originally from Omaha, moves into the apartment next to Leonard and Sheldon’s. Leonard soon adds another objective; be Penny’s boyfriend.

The top nerd of the four friends is definitely Sheldon; he knows and has no problems to show he is the most intelligent. Even when Penny is around he corrects her and points out the difference in intelligence. Leonard is probably the most “normal” of the four. He is the most knowledgeable of the social activities and rituals of “normal” people and considering Wolowitz is a flirt and Rajesh can only speak to women when drunk, Leonard is the one who better socialize with Penny than the rest.

At first I thought Penny was way too stupid; I understand most of what the nerd friends say is incomprehensible but no matter what she should know at least something about comics and their heroes. I too, am not a fan of comics (more of mangas) but I sure know batman, superman and all the others.

Still, I can relate to Penny most of the time. Especially when they start talking all physics and math. There I too am kind of stupid. But considering the names of all the episodes relate to various scientific terminology, and even bear relation to the events of the episode, sometimes I do come out with useful information. A weird thing I just noticed, Penny last names was never given. This might be intentional; it might be revealed when she becomes an actress or probably she marries one of the four friends, considering the events, Leonard.

Sheldon frequently wears T-shirts with the characters or symbols of Superheroes. He also occasionally wears t-shirts featuring a specific color with a corresponding symbol. These shirts are from the “Green Lantern” comic book series, with each color representing a different corps of heroes or villains . In the comics, each color also represents a specific emotion: Red=Anger, Orange=Greed, Yellow=Fear, Green=Willpower/Courage, Blue=Hope, Indigo=Compassion, and Violet=Love.The color of shirt Sheldon wears in each scene is often a clue to his mood.

Sheldon also introduced a new word to our vocabulary: Bazinga. The videos below will tell much more than I can.

The theme song is amazing. Barenaked Ladies wrote and recorded the theme song, which describes the development of the universe and the changes that the Earth and humans have undergone since the dawn of time, according to the eponymous theory, and the history of life according to the theory of evolution.

One of the most funniest episodes is The Lunar Excitation Episode, where Penny’s new boyfriend wants to see guy’s new experiment.
